drm: Implement vga_switcheroo_client_ops.post_switch

Browse source

An output's attached display might have changed while a DRM client's
device did not have the output switched to it.

The nouveau_switcheroo_reprobe() callback sends a hotplug notice to
DRM's internal clients, so that they can reconfigure their display
output if necessary.

As post_switch callback replaces reprobe in vga_switcheroo, update
nouveau accordingly. In the other drivers, remove the NULL-assignment
to reprobe. No functional changes.
